Hi I have a simple question. I want to run a "n times" a simple linear regession and save beta in a matrix but I´m not able. Imagine: Data.txt is a 10*5 file and want to run 4 different stimations always regressing first column on the rest. So I try this: First I run Data on memory This is my function mrp <- function(){ mr<-matrix(0,4,1) for(i in 1:4)

If I do > example(lm) ... > mycoef <- function(object, ...) UseMethod("coef", object) > mycoef(lm.D9) Error in mycoef(lm.D9) : no applicable method for "coef" which is pretty surprising, as coef has a default method. After a bit of digging, this comes from do_usemethod having defenv = environment where the generic was defined */ defenv =

Hi, I'm using R to do a time series analysis. In the model, I use the lags of some variables. such the lags of the variables have different length, I just can't use them directly in the lm function. Intuitively, I feel that "subset" might be useful, but I do not know how to use it. Anyone can give me an example syntax? Thanks. Harry [[alternative HTML version deleted]]

Hi all, I´m re-starting (as my name indicates) my little knowlegde of CRAN R. I made this function time before but I don´t know where is the error because nothing appears as an error but the histogram plot doesn´t appear. Should I install some special library to run sapply? pru<-function(){ randz<-matrix(rnorm(200000),100,2000) H<-matrix(0,100,2000) for (j in 2:2000){ for (i in

Any better (more efficient, built-in) ideas for computing coef[1]+coef[2]*x+coef[3]*x^2+ ... than polynom <- function(coef,x) { n <- length(coef) sum(coef*apply(matrix(c(rep(x,n),seq(0,n-1)),ncol=2),1,function(z)z[1]^z[2])) } ?

Hi all, I want to make the following: I want to run a linear regression on each column of a matrix "estima" on the correspondent column on the matrix "estima2". You see I want to regress estima[,1] on estima2[,1] this way to all columns.... At the same time I want to make a regression adding each time a new observation. You see, the first regression will regress only one

Hi, Correct me if I am wrong but there doesn''t seem to be an easy way to add validation outside the pre-built ones (validates_presence_of, validates_lenght_of, etc.). Ideally there should be something like: Class Person < ActiveRecord::Base validates :my_method, :on => create, :message => ''was not valid'' def my_method(param) false unless

I''d like to be able to run both development and production as follows: www.mysite.com will be running production dev.mysite.com will be running development It should run the same code base. The server is RedHat Enterprise 3, Apache, FastCgi. My problem is I don''t know where to set the environment so the application bootstraps depending on the virtual host (www/dev).

Since moving from 4.4 to 4.6, I've been seeing an increasing number of stability issues on our hypervisors. I'm not clear if there's a singular root cause here, or if I'm dealing with multiple bugs. One of the more common ones I've seen, is a VM on shutdown will remain in the null state and a kernel bug is thrown: xen001 log # xl list Name

Thanks for the heads-up. It's been

I have a Nvidia NVS310 installed in my Linux computer for a few years. It works well with the Nvidia driver, and not so well with the Linux nouveau driver. The Nvidia NVS310 has never worked well with Linux. In the beginning (many years ago) I decided to install Nvidia proprietary drivers, but every kernel upgrade would require an additional effort to have the driver working. That was enough

Hello CentOS Xen Heroes, Yesterday, I have installed testing kernel 4.9.23-26.el6.x86_64 from virt-xen-testing repo. It crashed today morning. Hardware is a pretty ancient, testing machine (CO6 PV guests only), but had no problems yet. It was stable on 4.9*, including testing 4.9.15-22.el6.x86_64 Console output: [59826.069427] general protection fault: 0000 [#1] SMP [59826.069463] Modules

Looks like I can reproduce this pretty easily, this happened upon ssh'ing into the server while I had a VM migrating into it. The system goes completely unresponsive (can't even

This only saves the @person but not the @address. Shouldn''t it save both? @person = Person.new(params[:person]) @address = Address.new(params[:address]) @person.address << @address @person.save here is what I have: class Person < ActiveRecord::Base has_many :addressables has_many :addresses, :through => :addressables end class Address <

I'm trying to get the Syspro/Encore MRP software running on a new CentOS 5 x86_64 system which uses an ODBC package built with old glibc/errno libraries. I have this same software running on a Suse Linux Enterprise 9 SP3 system using LD_ASSUME_KERNEL=2.4.1, but when I try this on CentOS 5 it results in many unidentified libraries including libc.so.6, librt... etc. My guess is that there are

I have an XP box that is hosting our MRP server software with the databases on a Centos 5 machine via samba. I was running all my apps on it as well. I decided to dedicate that machine to the server software and got a Win7 machine for my apps, databases still on the centos box. I changed the name of the XP machine to "server", it still logs into samba with my credentials. The Win7
